Bond Behaviour of Corroded and CFRP Repaired RC Beams Subjected to Monotonic and Repeated Loading
(University of Waterloo, 2012-09-27)All reinforced concrete (RC) design theories are based on the assumption that concrete exhibits a perfect bond with the steel reinforcement. The bond between steel and concrete is essential to the transfer of the load ... -
Bond of Corroded Reinforcement in Partial Depth Repairs in Reinforced Concrete Elements
(University of Waterloo, 2017-08-29)The bond in a reinforcement concrete (RC) structure is represented by the force transfer between the reinforcing bar and the surrounding concrete. All the RC structures are designed to have a perfect bond between the ... -
Development, Analysis and Testing of Innovative Mechanical Prestressing Anchors for CFRP Plates for Structural Rehabilitation and Retrofitting
(University of Waterloo, 2017-01-18)This thesis presents the development, analysis and experimental investigation of three innovative, easy-to-install, low cost, epoxy-free, mechanical, friction-based, compact, high-strength, prestressing anchors for carbon ... -
Finite Element Modelling of RC Beams Strengthened with Prestressed NSM CFRP Plate
(University of Waterloo, 2021-04-30)Near Surface mounted (NSM) carbon fibre reinforced polymer (CFRP) reinforcement has become a promising flexural strengthening technique for reinforced concrete (RC) elements. The prestressing of a CFRP plate can be used ... -
Flexural Fatigue Behaviour of Corroded Pretensioned Beams and Their Repair Using Carbon Fibre Reinforced Polymer Sheets
(University of Waterloo, 2015-09-24)The study presented in this thesis investigated the flexural fatigue behaviour of non-corroded and corroded pretensioned beams and examined the use of externally bonded Carbon Fibre Reinforcement Polymer (CFRP) sheets as ... -
Investigating the effects of glass-fibre-reinforced polymer fabrics and bars on the flexural behaviour of sawn timber and glulam beams
(University of Waterloo, 2023-09-11)As climate change becomes an increasingly pressing issue worldwide, the buildings and construction industry remains to be a significant contributor to global carbon emissions. To address this, construction materials with ... -
Micromechanical Modelling of Local Failure and Ply Crack Formation in Fiber-Reinforced Plastic Laminates
(University of Waterloo, 2022-01-26)Establishing an understanding of the multiscale nature of progressive failure in laminated fiber-reinforced plastics is required to develop high fidelity failure prediction models for associated structures. In recent years, ... -
Monotonic and Fatigue Performance of RC Beams Strengthened with Externally Post-Tensioned CFRP Tendons
(University of Waterloo, 2007-05-04)External post-tensioning is an attractive technique for strengthening reinforced concrete structures because of its ability to actively control stresses and deflections, speed of installation, minimum interruption for the ... -
Numerical Analysis of Debonding Mechanisms of Externally Bonded FRP Reinforcement in RC Beams
(University of Waterloo, 2018-04-16)There is an urgent need to develop economic and efficient methods to repair and strengthen existing reinforced concrete structures. This demand is motivated by several factors including the aging of concrete structures, ... -
Tests on Concrete Beams with GFRP Flexural and Shear Reinforcements & Analysis Method for Indeterminate Strut-and-Tie Models with Brittle Reinforcements
(University of Waterloo, 2014-12-18)This thesis is a summary of research on the use of glass fibre reinforced polymer (GFRP) bars and stirrups as internal reinforcement for concrete beams. Fibre reinforced polymer bars are geometrically similar to conventional ...
